wait a minute..

here's a test case I was actually working on (and which is running right 
now)

given 

[ :operator     :RXPelvisOfHipInjury;
  :precondition [ owl:intersectionOf ( :ConfirmNonPregnancy 
:PhysicalExamOfHipInjury ) ];
  :action       [ owl:intersectionOf ( :CADMeasurement :Diagnosis ) ];
  :effect       [ owl:unionOf ( :InsertHipBolt :ReplaceHip 
:RevalidationOfHipContusion ) ] ].

then I would really like to see the query equivalent with

[] q:select {?X :andStep ?Y};
   q:where  {?S :operator ?X; :effect ?A. ?A owl:intersectionOf ?L. ?L 
o:item ?Y}.
[] q:select {?X :orStep ?Y};
   q:where  {?S :operator ?X; :effect ?A. ?A owl:unionOf ?L. ?L o:item 
?Y}.

returning

:RXPelvisOfHipInjury :orStep :InsertHipBolt. 
:RXPelvisOfHipInjury :orStep :ReplaceHip. 
:RXPelvisOfHipInjury :orStep :RevalidationOfHipContusion.

experience?



While the lack of support for accessing collections has been
noted in various places, we didn't identify it as a requirement
(or even an objective) in http://www.w3.org/TR/rdf-dawg-uc/ .
If anybody now thinks it's a v1 requirement, speak now or
forever hold your peace.

It's also in order to share design ideas.

But assuming no lightbulbs go off in such a way as to
gain consensus, due to lack of design/implementation experience
I propose we postpone this issue.
